The male connector plug-in housing 201 is provided with a locking groove 209 matched with the locking piece in a locking way. The locking piece is assembled on the female connector plug-in housing 101 in a sliding manner along the radial direction of the female connector plug-in housing 101, and the sliding stroke of the locking piece has a locking position for locking the male connector 2 and the female connector 1 and an unlocking position for releasing the locking effect. As shown in fig. 14 to 17, the lock member includes a lock portion 113 for locking engagement with a lock groove 209 on the male connector 2, and the lock member further includes a press unlocking portion 112 for pressing the lock member to move the lock member away from the lock position, and the press unlocking portion 112 and the lock portion 113 are disposed opposite to each other in the lock member sliding direction, and the direction of the arrow shown in fig. 4 is the pressing direction of the press unlocking portion 112. The female connector housing 101 is provided with an elastic member for applying a radial elastic force to the locking portion 113 to hold the locking portion 113 at the locking position, and the elastic member in this embodiment is a conical spring 111 press-fitted between the female connector housing 101 and the press unlocking portion 112.

In order to avoid the over-compression of the conical spring 111 and the adverse effect of the spring back, the locking member of the present embodiment is provided with a stopping portion 114 for stopping and matching with the female connector insertion housing 101 to limit the compression amount of the conical spring 111 when the unlocking portion 112 of the locking member is pressed. In order to limit the conical spring 111 in the axial direction of the female connector insertion housing 101, the stop portion 114 is a cylindrical structure inserted into a central hole of the conical spring 111, and a large diameter end of the conical spring 111 is disposed close to the axis of the female connector insertion housing 101, and a small diameter end is disposed far away from the axis of the female connector insertion housing 101.

The height of conical spring 111 in female joint plug-in housing 101 axial direction when the complete compression is only for the height of conical spring 111 round, conical spring 111 is compressible elasticity height at whole height under the natural extension state, compared with the elastic component adoption cylindrical spring among the prior art, conical spring 111's natural extension height is less than cylindrical spring's height far away under the condition of same amount of compression, correspondingly, the size of locking piece installation department 110 along female joint 1 radial direction that sets up on female joint plug-in housing 101 also reduces greatly, do benefit to the miniaturized design of female joint 1.
